MOTOR ATTACHMENT FOB; SEWING MACHINES.

Application filed October 29, 1921.

T0 aZZ whom it may concern Be it known that T. Fosrnn F. HILLIX, z. citizen of the United States, residing at Cleveland. in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Motor Attachments for Sewing Machines, of. which. the following is a full, clear, and exact descrip tion.

This invention relates to a motor attachment for sewing machines. and has for its chief object to provide an attachment wherein the motor is supported from the arm of the sewing machine head in a man er such that a compact arrangement is provided, with the motor so situated that it does not extend outwardly beyond the bed of the machine, and thus will not require an enlargement of the case when the invention is ap plied. to a portable sewing machine, and will not interfere with the swinging movement of the head of the machine when the invention is applied to sewing machines of the drop head type.

In accordance with my invention, the motor is attached to the vertical part of the arm of the head, with the housing of the motor located off to one side of the said vertical portion, and partly underneath the horizontal portion of the arm so as to project laterally beyond the head a relatively short distance only.

In the accompanying sheet of drawings showing one form of the invention, Fig. 1 is a side view of a portion of the head of a sewing machine equipped with my invention; Fig. 2 is an end view of the same; and Fig. 3 is a section on the line 3-3 of Fig. 1, looking in the direction indicated by the arrows.

Referring now to the drawings, represents the bed of the sewing machine head, 11 the vertical portion of the arm, 12 the horizontal portion thereof, and 13 the hand wheel. The head may have any suitable construction as far as these and other parts thereof are concerned, and it may be applied to a sewing machine of what is known as the portable type, or to a non-portable machine of the drophead or other type. However, the invention is especially useful in a portable machine or a machine of the drop-head type, for with machines of these types the Serial No. 511,355.

advantages of the invention are attained to the highest degree.

In this instance the machine is driven by an electric motor 14;, which is supported on the vertical portion 11 of the arm, but instead of the housing or body of the motor being opposite the vertical portion as it would be ordinarily when the motor is attached to the vertical part of the arm, the end of the motor housing is provided with a special supporting bracket 15 which projects from the end of the motor housing, this bracket being secured to the vertical portion of the arm by screws 16 or equivalent means. The length of this bracket is such that the housing or body part of the motor is to one sideof the vertical part of the arm, and the manner in which the bracket extends out from the motor housing is such that when the bracket is secured to the upright portion of the arm of the head. the motor per se lies partly under the horizontal portion 12 of the arm so that it projects virtually a minimum distance laterally of the head. In fact, it will be observed from Fig. 2, that itdoes not project outwardly beyond the bed 10, and therefore a very little distance beyond the hand wheel so that this mounting will not require a special case when the invention is applied to a portable machine or an enlargement of the case, and will not interfere with the swinging movements of the head when it is applied to a machine of the drop head type.

The bracket 15 has a bearing for an extension of the motor shaft, and to the outer end of this extension suitable motor driving means may be provided. This may assume different forms, but in this instance I provide on the end of the motor shaft extension, a supporting pinion 17 which engages a gear 18 which is attached to, and rotates with the hand wheel 13. The gears are preferably enclosed in a guard 19 which may assume the form shown in Fig. 1.

Thus it will be seen that inasmuch as the motor, though supported on the upright arm of the head, projects well underneath the horizontal portion thereof, the objects of this invention are attained very effectively.

Having described my invention, I claim:

1. The combination with a sewing machine head having an arm with upright and horizontal portions, a driving motorfor the machine, said motor being supported in operative position from the arm and located partially beneath the horizontal portion thereof.

2. A motor attachment for a sewing machine head having a hand wheel comprising a motor secured to the upright portion of the arm of the head and operatively connected to the hand wheel, and located to the side of said upright portion of the arm opposite the hand wheel.

eeaeee 3. The combination with a sewing machine head having an arm with upright and horizontal portions, a motor attachment comprising a motor in driving engagement with the head, said motor being attached to the upright portion of the arm and being located partially beneath the horizontal portion thereof.

In testimony whereof, I hereunto affix my signature.

FOSTER F. HILLIX.
